Tennis ball cricket: Pitch Length

Hi All,

Have a couple of questions:

1. To all Tennis ball cricketers:

I have a question on the pitch length. We play with hard tennis ball (sometimes taped). We generally set the pitch to 20 yards, instead of 22.
Have seen many other teams also play with 20 yards. However some players in my team feel we should play @ 22 yards. What do you guys think?

What should be the ideal pitch length if playing with tennis ball?

2. Wide rule when bowling around the wicket:

My understanding is that the wide rule is same irrespective of whether the bowler bowls over or around the wicket. But I recently heard that in case of around the wicket, there is a different wide marker. Is that true?

Pitch length is 20 meters. The tennis ball fur is usually scorched before playing, so ball comes quick and skid. Only tall bowlers with shoulder strength can make it bounce, or people who make the ball grip on the surface. Wide is one bat width usually.
